This commit was fine, though the commit log is misleading since there's
no dereference yet, just a pointer calculation. I may not have seen that
at the time, or have decided that the slight commit log inaccuracy
didn't matter.

I'm inclined towards keeping it, since it removed a BUG_ON(), but
there's no reasonable scenario where somebody could end up calling this
function with a NULL pointer.
